This is a study about gender differences and the first of its kind to look at sex-related differences in and determinants of access to care within a population of younger people who have had heart attacks, McGill University psychologist Dr. Roxanne Pelletier, lead author, told me. "In the last decade the incidence of heart attacks have been increasing in younger people and even more quickly in women compared to men. Our team thinks that gender-related characteristics play a role in that."
